Cov alleles uas tsim cov noob caj noob ces, paub ua ke raws li ib tug genotype, muaj nyob rau hauv khub uas zoo tib yam, hu ua homozygous, los yog mismatched, hu ua heterozygous. Thaum ib tag hmo alleles ntawm ib khub heterozygous daim npog qhov ncauj lub xub ntiag ntawm lwm tus, recessive allele , nws yog lub npe hu ua a tseem ceeb allele.

Ua kom qhov no nyob rau hauv saib, uas allele yog recessive?

Recessive Recessive yog qhov zoo nyob hauv kev sib raug zoo ntawm ob lub versions ntawm a noob . Cov tib neeg tau txais ib qho version ntawm a noob , hu ua allele, los ntawm txhua tus niam txiv. Yog hais tias cov alleles txawv, cov tseem ceeb allele yuav raug qhia, thaum cov nyhuv ntawm lwm cov allele, hu ua recessive, yog npog.

Tsis tas li ntawd, vim li cas qhov tseem ceeb ntawm alleles tau nthuav tawm tshaj qhov tsis txaus ntseeg? Dominant txhais tau tias yog koj muaj ib daim ntawv luam ntawm ib qho allele , tsis muaj txoj hauv kev uas tsis yog kuaj DNA los qhia seb koj puas tau txais ib daim qauv ntawm lwm tus allele ntawm qhov chaw. Rov qab txhais tau tias koj yuav pom tsis muaj laj thawj ntseeg li ntawd allele tam sim no tsuas yog muaj 2 daim ntawv theej allele.

Thiab cov lus nug yog, dab tsi yog qhov tseem ceeb ntawm allele thiab recessive allele?

Genes tuaj nyob rau hauv txawv versions, los yog alleles , nrog tseem ceeb alleles raug qhia tshaj recessive alleles . Recessive alleles tsuas yog qhia thaum tsis muaj tseem ceeb allele yog tam sim no. Hauv feem ntau cov kab mob sib deev, txhua tus neeg muaj ob alleles rau txhua tus noob (ib qho los ntawm txhua tus niam txiv).

Leej twg muaj zog genes niam lossis txiv?

Niam txiv noob muaj tau pom muaj ntau tseem ceeb tshaj cov niam cov txiv. Cov noob ntawm koj txiv muaj ntau tseem ceeb dua cov tau qub txeeg qub teg ntawm koj niam , kev tshawb fawb tshiab muaj qhia.
